Re^6: Inverting test conditions in Test::More ?

The test data is generated, finding the difference manually isn't easy.

Furthermore, the idea of having Boolean logic for tests is straightforward and makes the code elegant and readable.

Most importantly it's generic, I can't tell which other test besides is_deeply doesn't provide a negation.

And I learned a lot about the test suite, especially Test::Builder in the course of this thread, just by asking this "silly question".

I can't tell which other test besides is_deeply doesn't provide a negation. From Test::More I would offer: `use_ok` `require_ok` `isa_ok` `can_ok` none of which have a negative. Technically `ok` doesn't have a negative either but the trivial workaround of negating the argument should be sufficient for that one. 🦛	[reply] [d/l] [select]

There are so many more `Test::` modules out there probably not as well designed as Test::More. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]
